The Pima County Sheriff's Office has created a web link for people with images and videos that can help locate Nancie Guthrie, 84, presumed kidnapped.

Investigators searching for Nancy Guthrie, the mother of Today show co-anchor Savannah Guthrie, have not identified any suspect or person of interest in the case, pushing back against speculation circulating online.

The incident comes after the killing of 37-year-old Alex Pretti, an ICU nurse shot multiple times by federal immigration agents on Saturday in Minnesota.

The AZDPS says there are serious injuries.
